I am trying to pass the content of a global variable to an HTTP-in node  
In my template node I have the following:

```auto
{
Learning status: {{global.get("LearningStatus")}}
}

```

but it is giving error when the request is sent to the HTTP-in node.  
"Invalid property expression: unexpected " at position 4"

How can I pass the value of the global variable to the template node in the correct way?  
Thanks for helping.

Properties can not contain spaces, not sure if this is the source of the error but that should be solved at least.

Thanks for highlighting the typo. I corrected it but the problem is still the same.  
it reads like this now:

```auto
{
Learning_status:{{global.get("LearningStatus")}}
}

```

Invalid property expression: unexpected " at position 4

</div>

In a template node it would be

```auto
{
Learning_status: {{global.LearningStatus}}
}

```

and if you wanted valid json  
it would be

```auto
{
"Learning_status": "{{global.LearningStatus}}"
}

```

Depending thee value of global.learningStatus.

Thank you.  
I don't get errors anymore but still I cannot get the value of the global.LearningStatus.  
I get **"Learning\_status": "[object Object]"** rather than the real value which is "Process stopped" or "Process started".  
I tested the value of the global.LearningStatus and it is correct. I tested both the code you suggested but same result. Not sure about what this issue is now.

Then global.learning\_status is an object. Show us the global value in the sidebar.

That is not the context sidebar that is the debug sidebar. We need to see what the global is set at.

Again that is a change node, we need to see the context sidebar . at top of the sidebar select the icon that looks like 3 coins and then refresh global and show us the result.

[edit]  
I suspect it is `global.learningStatus.Status`.  
in your change node you should of set  
`global.learningStatus`  
to  
`msg.payload.Status`.  
If you wanted the value at `global.learningStatus`

In the template node now I have

```auto
"Learning_status": "{{global.LearningStatus.status}}"

```

In the change node I have set the variable to msg.payload.status  
If I send the request I get: "Learning\_status": ""  
The value of the variable is not there yet. Sorry for bothering you with this

Capital S for Status in `msg.payload.Status`, and use `global.learningStatus`
